So I'm looking to buy a MIDI-keyboard, and my eye has fallen on a second-hand €120 Kawai M8000.
Only problem is, 4 keys don't register. Would it be possible to repair this myself? If it's just rust or disintegrated rubber I can probably do it myself, but if the problem is in software then it'll be a pig in a poke. Can't find much information on the internet about repairing keyboards.
Should I take the leap?

I'll check for a service manual a little later.
If we have one in PDF format, I'll be happy to email it to you.

Cheers,
James

Depending on how handy you are, you can fix all sorts of hardware problems. I bet you could swap the rubber domes or even maybe the switches from a working key in a less-useful location for the ones that no longer work.

A service manual would be awesome, I can only find the regular manual on the internet.
Switching parts from the broken keys to the less used keys is something I hadn't thought of already, thanks for the suggestion. I'll probably get my parents to help me pick it up, as the keyboard+case is 105 lbs...

I'm afraid I am unable to send the service manual.

However, there appear to be a handful of sites selling it online.

Kind regards,
James

50 KGs was pretty heavy to carry down two sets of stairs but we made it. Here's a picture with the keyboard already upside down:

Managed to break another 4 or five keys while opening it and toying around, and some keys need to be hit rather hard to register, so maybe it's dust. The rubber domes are in excellent state though.
I'll be completely disassembling it and cleaning all the dust and rust to see if that'll help.

And would anyone here happen to know what this connector is for? It has 4 wires going to the circuit boards, and is attached to something under the felt of the keyboard. Tapping it while playing doesn't seem to do much.

Hey Guys,

Sorry to dig up an old thread! Just picked up on of these today for $50. Seems the volume control works, and I get "reset" + various commands when I turn the system on.. but key presses don't generate any output. Stop/starting sync also sends clock commands. Any idea why it wouldn't be generating output? Is there a way to reset the memory?

If somebody needs parts and is seriously interested in fixing one of these.
I have one that is broke. Many good parts though.
I'd be willing to let it go for free. But you have to pay for the shipping and packaging. I'll just take it to a UPS store. Probably won't be cheap.
These M8000's are too good. I don't want to see mine just go to waste.

Ron, I'm tempted to take you up on that. I'm going to see how far I can get with the service manual first. If anyone needs a copy, I've uploaded it here:
